Element centroid computation is returning 0.0 with a 24 picpart run on 288 gpus with 6 planes and 2 processes/picpart. The vtu files produced by xgcp mesh render(...) are invalid for picparts 22 and 23 (the last two). If only the coordinate information were incorrect in these vtu files they would still render. This may indicate that the mesh topology is the problem; I'm guessing the vtu files only contain element to vertex downward adjacencies.

update: The centroid check was broken.
